FOLDING ARM FOR AWNINGS.

To all whom it may concern Be it known that I, FRANK 1W1. CHRISTIAN, acitizen of the United States, residing at Seattle, in the county of Kingand the State of Washington, have invented a new and useful Folding Armfor Awnings, of which the following is a specification.

My invention relates to improvements in devices adapted to supportawnings in front or over the windows, doors or store fronts of abuilding which devices are adapted by their form and structure to foldsuch awning or permit it to be rolled into a snug and compact formwhereby it may be stowed close to the wall of a building; but moreparticularly my invention comprises an improvement on a folding awningarm which is described and illustrated in my co-pending application forUnited States Letters Patent filed January 21, 1912, the serial numberof which is 673,212; and the object of my present invention is toprovide a folding-arm support for awnings which shall be adapted tobetter extend an awning outwardly from a building for a greater distancethan can be done by the device of my co-pending application abovereferred to. I attain such object by a form of structure illustrated inthe accompanying drawings, wherein Figure 1 is a plan View, on a reducedscale, of my invention showing it applied to an awning when such awningis fully extended from the wall of a building, Fig. 2 is a view of thesame, on a larger scale, in side elevation, Fig. 3 is a view of the samein side elevation showing the position of its movable parts as theywould appear at one point of'their movement in the operation of foldingand Fig. 4. is a view in side elevation as it would appear when foldedback against the wall of a building.

Like reference numerals indicate like parts throughout the drawings.

Referring now to Fig. 2 of the drawings 5 indicates the wall of abuilding to which is fastened a supporting bracket 6, from the upper endof which projects a lug 7 and from the lower end of which projectsanother lug 8. Hinged to such lower lug 8 by a pivot 9 is a bar 10 whileanother bar 11 is hinged at one of its ends to the upper lug 7 by apivot 12. The end of the bar 10 distant from the pivot 9 is providedwith a lug 13 which is riveted to the end of the bar 10 by a rivet 14.Pivoted by a pivot 15 to the Specification of Letters Patent.

upwardly projecting portion of the lug 13 1s a lever-16 whose shorterarm, extending obliquely upward, is connected with the outer end of thebar 11 by a link 17 by means of pivots 18 and 19 respectively. Thelonger arm of the lever 16 extending outwardly from its pivot 15 ishinged at its outer end to a bar 20 at a point near the center of saidbar 20. The innermost end of the bar 20 is provided with an upwardlyprojecting lug 21 which is secured thereon by a rivet 22. One end of aconnecting bar 23 is hinged at one of its ends to the upwardlyprojecting portion of the lug 21 by a pivot 24: while the innermost endof said bar 23 is hinged by a pivot 25 to the bar 10 at a point near thecenter of its length. The extreme outermost end of the bar 20 is adaptedto be secured to a cross-bar 26 which may extend between a pair offoldlng-arms, as more clearly shown in Fig. 1; such cross-bar 26 isadapted to have attached to it the outer edge of an awning 27 which mayextend from said crossbar 26 obliquely to a roller mechanism 28 of wellknown form which roller mechanism 28 may be adapted by obvious means notshown to roll up the awning 27 thereon.

If a structure embodying my invention be disposed as shown in Figs. 1and 2, then, in its operation, at the commencement of the rolling of theawning 27 on the rolling mechanism 28 the outer end of the bar 20 wouldcommence to swing upwardly and its inner end with its lug 21 would swingdownwardly, while the bars 10 and 11 would swing upwardly, andcontinuing such rolling of the awning 27 such bars would reach aposition as shown in Fig. 3, and when the awning 27 is completely rolledup both foldingarms would be folded compactly against the wall 5 withtheir parts in the position shown in Fig. 4.

It will thus be seen that my present invention comprises the addition ofthe bar 20 and the connecting bar 23 to the structure illustrated anddescribed in my co-pending application hereinbefore mentioned.

What I claim is:

In a folding-arm of the class described, the combination with a verticalsupport adapted to be fastened to the wall of a building, of a lever ofan angular shape, an arm hinged at one of its ends to the upper endportion of said support while its other end is connected by a link withone end of said lover, a second arm hinged at one of its ends to thelower end portion of said support While its other end is hinged to saidlever at the point of junction of the two arms of said lever, an outerextension bar hinged near its central portion to the enter end of saidlever, the innermost end of which her is hinged to a connecting; barwhich extends therefrom to the central por- FRANK CHRISTIA N.
